    Abstract: A method of treating an exhaust gas produced by a vehicle internal combustion engine includes conveying the gas through a first reactor including a non-thermal plasma. The gas includes nitric oxide and is transitionable between a first condition in which the gas has a cold-start temperature that is less than or equal to about 150° C., and a second condition in which the gas has an operating temperature that is greater than about 150° C. During the first condition, the method includes contacting the gas and plasma to oxidize the nitric oxide to nitrogen dioxide and form an effluent that includes nitrogen dioxide. The method includes concurrently conveying the effluent through a second reactor including a diesel oxidation catalyst, and storing the nitrogen dioxide within the second reactor during only the first condition. The method includes, after storing, releasing nitrogen dioxide from the second reactor during only the second condition.

    Abstract: A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.

    Abstract: A system for controlling fluid temperature in a thermal system includes a heat source, a heat sink coupled to the heat source, a first heat exchanger and a second heat exchanger, a first expansion valve configured to regulate the flow of coolant between the heat source and the first heat exchanger, a second expansion valve configured to regulate the flow of coolant between the heat source and the second heat exchanger, and a controller. The controller is configured to determine an operating condition of the thermal system and generate a first control signal to control the first and second expansion valves to direct the flow of coolant to the first and second heat exchangers. The first and second expansion valves are arranged in parallel to recover heat rejected from the coolant and distribute the recovered heat to the first and second heat exchangers.

    Abstract: The present disclosure provides an engine cooling system for controlling the temperature of an engine of a motor vehicle. The system includes an engine cooling circuit for circulating a coolant to transfer heat from the engine to an airflow. An electric water pump is configured to circulate the coolant through the circuit at a maximum electric pump flow rate, and a mechanical water pump is configured to circulate the coolant through the circuit at a maximum mechanical pump flow rate that is higher than the maximum electric pump flow rate. The circuit further includes a selector valve configured to fluidly connect one of the electric water pump and the mechanical water pump to the engine. An engine control module generates a valve signal for actuating the selector valve to fluidly connect one of the electric water pump and the mechanical water pump to the engine.

    Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.
